NFO Servers Support wrote:When any TS3 server is started up, it contacts the main TS3 accounting server to verify that it is allowed to run and to report its slot count. If the main accounting server can't be used, it falls back to using a secondary accounting server. If neither accounting server can be reached, the server keeps trying, then restarts itself after two hours.

Currently, the main TS3 accounting server is unresponsive -- requests to it are being dropped. The secondary TS3 accounting server just isn't set up yet by the developer of TS3. This means that many servers are restarting themselves every two hours.

We have opened a ticket with TeamSpeak Support to ask them for an ETA on when this problem will be resolved.
